Update template dependencies

[Rek-Malorm]

This PR bumps the dependency versions to align with latest at the time of this PR.
This includes some minor refactor to support changes in these dependencies

I think PR is started to get out-of-date; I had to use wasm-bindgen 0.2.95 to avoid build errors. When are we going to merge the PR?

[Rek-Malorm]

wasm-bindgen is constrained by what was used when installing either trunk or cargo-leptos (Can't rememebre which)

None the less this is derived from what is used in the main examples found here

It may be better to include this example in with the rest but that would be up to the maintainers.
I created this because I spent too much time trying to work it out myself

How can we "encourage" the leptos team to merge this?

[CorvusPrudens]

The issue with this PR is that it too is now out of date by quite a bit.

If this is still useful despite being out of date, please let me know and we can merge it as-is.

[Rek-Malorm]

I agree with Corvus. I'm not entirely sure this is worth merging in as that does not solve the issue of this repo. The issue is its unmaintained.

Instead of merging this in, could we instead include the content of this repo in the examples of the main repo? The vast majority of changes are identical to what other examples need. So surely it won't hurt to shift where this lives?

That's a great idea! The Leptos docs point here but it would be much better if there were a solution in examples.
